Read multiple xml nodes by JAXB / converting xml to object

Using JAXB we can read/write the multiple xml nodes.

consider a scenario where u have to read the list of items from the file system, then its better option is to use JSON or XML structure.

Full sample of the JAXB reading the list of object from the xml file.

	import javax.xml.bind.annotation.XmlAttribute;
	import javax.xml.bind.annotation.XmlElement;
	import javax.xml.bind.annotation.XmlRootElement;
	/**
	*
	* @author Rivet Systems
	*/
	@XmlRootElement
	public class Customer {
	String name;
	String email;
	int id;
	public String getName() {
	return name;
	}
	@XmlElement
	public void setName(String name) {
	this.name = name;
	}
	public String getEmail() {
	return email;
	}
	@XmlElement
	public void setEmail(String email) {
	this.email = email;
	}
	public int getId() {
	return id;
	}
	@XmlAttribute
	public void setId(int id) {
	this.id = id;
	}
	}
